SPRING-EQUALIZER FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 365,884, dated July 5, 1887.

I Application filed October 21, 1886. Serial No. 216,849. (No model.)

To all whom it may concern:

Be it known that we, THOMAS D. TOY, JAMES M. ToY, and NELsoN TOY, citizens of the United States, residing at Oherryvale,in the conntyof Montgomery and State of Kansas, have invented certain new and useful Improvementsin Spring-Equalizers for Vehicles; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The invention has for its object the combination of instrumentalities between the bed or bottom'of a vehicle and a side-bar frame so that the weight wherever placed will automatically distribute itself.

Figure l of the drawings is a bottom view, Fig. 2 a cross-section, and Fig. 3 adetail view, of the couplings.

In the drawings, A A are the cross bars on a pivot, B; O, the couplings; D D, the end springs; E, the side-bar frame; F, the bed of vehicle-body, and G G staples which fasten the middle of springs to the bed.

In a longitudinal median line of the'bed F, at the front and rear, we place the transverse fiat semi-elliptic springs D D, which are end slotted at d d to slide on bolts secured to the bottom of the side bars of frame E. Between these springs and across the middle of the bed F and the frame E we arrange the cross-bars, which are pivoted at their intersection and have end slots, a, which work on pivots h of the couplings O. The short arms of the rods are connected with the bed F, while the long arms are connected with the frame E. By combining with the end springs an intermediate pair of rigid cross-pivoted bars, A A, it willbe observed that the body is compelled to press down in the springs perpendicularly-,whether the weight shall be great or small. The body can neither sag to the right, left, forward, or back, but must go straight down; hence the weight is automatically equalizing, and will always bear with the same pressure upon one spring as upon the other.

What we claim as new, and desire to protect by Letters Patent, is-

The combination, with a vehicle-bed and a side-bar frame, of the slotted end springs, D D, and intermediate cross-pivoted bars, A A, the latter connecting the middle of bed with the middleof frame E, as shown and described.

In testimony whereof we affix our signatures \Vitnesses:
